Green HVAC for commercia buildings/warehouses/multi level residentials

ABSTRACT

A green HVAC system for single or multi level commercial or residential buildings including: 
     a building having a lower elevation and higher elevation.
         (i) The lower elevation blower that can blow air to higher elevation or outside of building ,or can suck air from higher elevation or outside of building   (ii) The higher elevation blower that can blow air to lower elevation or outside of building, or can suck air from lower elevation or outside of building

TECHNICAL FIELD

The present invention relates to green system for heating and cooling for buildings, and to building green heating and cooling systems that reduce energy usage.

SUMMARY OF THE INVENTION

The present invention provides a green system for heating and cooling for single or multi level building also can achieve thermal equilibrium between higher and lower elevation or multi level buildings. Higher elevation in any building has higher temperature than lower elevation based on the fact that hot air rises.

For heating, both higher and lower elevation air blower system can interact with outside air for rising temperature if outside temperature is higher than lower and higher elevation temperatures. Then in this case both higher and lower elevation air is replaced by outside air. If lower elevation temperature is only lower than outside temperature then lower elevation interact with outside temperature to replace lower elevation air with outside air. If both higher elevation and lower elevation temperature are higher than outside temperature, then there are no interaction with outside air. After the outside air exchange if any is done, then higher elevation air can be brought by higher elevation blower system into lower elevation while simultaneously lower elevation air is brought into higher elevation by lower elevation air blower system until there is a thermal equilibrium between higher and lower elevation or we reach pre-determined temperature.

For cooling, both higher and lower elevation fans assembly can interact with outside air for dropping temperature if outside temperature is lower than both lower and higher elevation temperatures. Then in this case both higher and lower elevation air is replaced by outside air. If higher elevation temperature is higher than outside temperature then higher elevation air is replaced by outside air. If both higher and lower elevation temperatures are lower than outside temperature then there is no air interaction with outside air. After the outside air exchange if any is done, then higher elevation air can be brought into lower elevation by higher elevation air blower while simultaneously lower elevation air is brought into higher elevation by lower elevation air blower until there is a thermal equilibrium between higher and lower elevation or we reach pre-determined temperature.

DETAILED DESCRIPTION OF THE DRAWINGS

FIG. 1 present a green technology for heating and cooling. This green technology interact with outside air exchange system and lower elevation, higher elevation air exchange can adjust temperature to be always closer to thermal comfort. Lower elevation air blower 60 consist of lower elevation outside air blower 20 and lower elevation air blower 21. Higher elevation air blower 70 consist of higher elevation outside air blower 30 and higher elevation air blower 31. A control system 40 is provided. Control system 40 controls the operation of air blower 20, 21, 30, 31 controlling when they are on or off also which direction they rotate. Also control 40 has temperature sensor for both lower and higher elevation. All the air blower 20, 21, 30, 31 may be powered by solar panels (or wind turbine) 42. The air exchange between higher elevation and lower elevation happens by air blower 21 and 31 through the air channel (duct/ducts) 50.

The system compromises a higher elevation air blower 31 for moving air from higher elevation to lower elevation. Also air blower 30 to take out air from higher elevation or bring outside air to higher elevation zone. Also compromises a lower elevation air blower 21 for moving air from lower elevation to higher elevation also air blower 20 to take out air from lower elevation or bring outside air to lower elevation zone.

Referring to FIG. 2 is for multi level buildings

The higher level always should contain air at higher temperature than lower level. This difference in temperatures, and monopolization with outside temperature, and air exchange between higher and lower level can bring both levels to temperature equilibrium.

Referring to FIG. 3 is for pitched roof buildings

The air blower assembly 70 is located in highest for optimum high temperature.

Reffering to FIG. 4 is for pitched multi level buildings
